What Are Limit Gauges?
What Are Limit Gauges? Limit gauges are used to check the dimensions of a manufactured component. As gauges are without scale, we are unable to use it to determine the actual size of dimensions of parts. They are different from a conventional measuring tool. We use a limit gauge to inspect whether a work piece is within the specified tolerance. They are also often known as a Go and No-Go gauge. A principle of using such gauges, is for the Go end to be used to check that the dimension of the part passes inspection. On the other hand, the No-Go gauge should not be able to pass the same dimension of the part. It serves as a check when a measured part fails inspection. Go and No-Go Gauge The Go- and No-Go gauges are produced according to the dimensions of the manufactured component. The Go gauge is usually equivalent to the minimum permissible dimension of the component. The No Go gauge is equivalent to the maximum permissible dimension of the measured component. ...
